DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

Embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Where possible, any terms expressed in the singular form herein are meant to also include the plural form and vice versa, unless explicitly stated otherwise. Also, as used herein, the term “a” and/or “an” shall mean “one or more,” even though the phrase “one or more” is also used herein. Furthermore, when it is said herein that something is “based on” something else, it may be based on one or more other things as well. In other words, unless expressly indicated otherwise, as used herein “based on” means “based at least in part on” or “based at least partially on.” Like numbers refer to like elements throughout.

As used herein, an “entity” may be any institution employing information technology resources and particularly technology infrastructure configured for processing large amounts of data. Typically, these data can be related to the people who work for the organization, its products or services, the customers or any other aspect of the operations of the organization. As such, the entity may be any institution, group, association, financial institution, establishment, company, union, authority or the like, employing information technology resources for processing large amounts of data.

As described herein, a “user” may be an individual associated with an entity. As such, in some embodiments, the user may be an individual having past relationships, current relationships or potential future relationships with an entity. In some embodiments, a “user” may be an employee (e.g., an associate, a project manager, an IT specialist, a manager, an administrator, an internal operations analyst, or the like) of the entity or enterprises affiliated with the entity, capable of operating the systems described herein. In some embodiments, a “user” may be any individual, entity or system who has a relationship with the entity, such as a customer or a prospective customer. In other embodiments, a user may be a system performing one or more tasks described herein.

As used herein, a “user interface” may be any device or software that allows a user to input information, such as commands or data, into a device, or that allows the device to output information to the user. For example, the user interface includes a graphical user interface (GUI) or an interface to input computer-executable instructions that direct a processing device to carry out specific functions. The user interface typically employs certain input and output devices to input data received from a user second user or output data to a user. These input and output devices may include a display, mouse, keyboard, button, touchpad, touch screen, microphone, speaker, LED, light, joystick, switch, buzzer, bell, and/or other user input/output device for communicating with one or more users.

As used herein, “authentication credentials” may be any information that can be used to identify of a user. For example, a system may prompt a user to enter authentication information such as a username, a password, a personal identification number (PIN), a passcode, biometric information (e.g., iris recognition, retina scans, fingerprints, finger veins, palm veins, palm prints, digital bone anatomy/structure and positioning (distal phalanges, intermediate phalanges, proximal phalanges, and the like), an answer to a security question, a unique intrinsic user activity, such as making a predefined motion with a user device. This authentication information may be used to authenticate the identity of the user (e.g., determine that the authentication information is associated with the account) and determine that the user has authority to access an account or system. In some embodiments, the system may be owned or operated by an entity. In such embodiments, the entity may employ additional computer systems, such as authentication servers, to validate and certify resources inputted by the plurality of users within the system. The system may further use its authentication servers to certify the identity of users of the system, such that other users may verify the identity of the certified users. In some embodiments, the entity may certify the identity of the users. Furthermore, authentication information or permission may be assigned to or required from a user, application, computing node, computing cluster, or the like to access stored data within at least a portion of the system.

It should also be understood that “operatively coupled,” as used herein, means that the components may be formed integrally with each other, or may be formed separately and coupled together. Furthermore, “operatively coupled” means that the components may be formed directly to each other, or to each other with one or more components located between the components that are operatively coupled together. Furthermore, “operatively coupled” may mean that the components are detachable from each other, or that they are permanently coupled together. Furthermore, operatively coupled components may mean that the components retain at least some freedom of movement in one or more directions or may be rotated about an axis (i.e., rotationally coupled, pivotally coupled). Furthermore, “operatively coupled” may mean that components may be electronically connected and/or in fluid communication with one another.

As used herein, an “interaction” may refer to any communication between one or more users, one or more entities or institutions, and/or one or more devices, nodes, clusters, or systems within the system environment described herein. For example, an interaction may refer to a transfer of data between devices, an accessing of stored data by one or more nodes of a computing cluster, a transmission of a requested task, or the like.

As used herein, a “resource” may generally refer to objects, products, devices, goods, commodities, services, and the like, and/or the ability and opportunity to access and use the same. Some example implementations herein contemplate a market value of a property held by a user, including property that is stored and/or maintained by a third-party entity. For purposes of this invention, a resource is typically stored in a resource repository—a storage location where one or more resources are organized, stored and retrieved electronically using a computing device.

As used herein, a “resource transfer,” “resource distribution,” or “resource allocation” may refer to any transaction, activities or communication between one or more entities, or between the user and the one or more entities. A resource transfer may refer to any distribution of resources such as, but not limited to, a payment, processing of funds, purchase of goods or services, a return of goods or services, a payment transaction, a credit transaction, or other interactions involving a user's resource or account. In the context of an entity such as a financial institution, a resource transfer may refer to one or more of: a sale of goods and/or services, a user accessing their e-wallet, or any other interaction involving the user and/or the user's device that invokes or is detectable by the financial institution. In some embodiments, the user may authorize a resource transfer using at least a resource transfer instrument (credit cards, debit cards, checks, digital wallets, currency, loyalty points), and/or payment credentials (account numbers, resource transfer instrument identifiers). Unless specifically limited by the context, a “resource transfer” a “transaction”, “transaction event” or “point of transaction event” may refer to any activity between a user, a merchant, an entity, or any combination thereof In some embodiments, a resource transfer or transaction may refer to financial transactions involving direct or indirect movement of funds through traditional paper transaction processing systems (i.e. paper check processing) or through electronic transaction processing systems.

As used herein, a “non-fungible token” or “NFT” may refer to a digital unit of data used as a unique digital identifier for a resource. An NFT may be stored on a distributed ledger that certifies ownership and authenticity of the resource. For purposes of this invention, a distributed ledger (e.g., blockchain) may be a database that is consensually shared and synchronized across multiple sites, institutions, or geographies, accessible by multiple people. A distributed ledger may be associated with independent computers (referred to as nodes) that record, share and synchronize transactions in their respective electronic ledgers (instead of keeping data centralized as in a traditional ledger). As such, NFTs cannot be copied, substituted, or subdivided. In specific embodiments, the NFT may include at least relationship layer, a token layer, a metadata layer(s), and a licensing layer. The relationship layer may include a map of various users that are associated with the NFT and their relationship to one another. For example, if the NFT is purchased by buyer B1 from a seller S1, the relationship between B1 and S1 as a buyer-seller is recorded in the relationship layer. In another example, if the NFT is owned by O1 and the resource itself is stored in a storage facility by storage provider SP1, then the relationship between O1 and SP1 as owner-file storage provider is recorded in the relationship layer. The token layer may include a smart contract that points to a series of metadata associated with the resource, and provides information about supply, authenticity, lineage, and provenance of the resource. The metadata layer(s) may include resource descriptors that provides information about the resource itself (e.g., resource information). These resource descriptors may be stored in the same metadata layer or grouped into multiple metadata layers. The licensing layer may include any restrictions and licensing rules associated with purchase, sale, and any other types of transfer of the resource from one person to another. Those skilled in the art will appreciate that various additional layers and combinations of layers can be configured as needed without departing from the scope and spirit of the invention.

The present invention leverages non-fungible token (NFT) technology to allow users, who are unable to physically approach an electronic kiosk (e.g., automated teller machine), to authorize a trusted dependent to execute resource transfers at the electronic kiosk using a resource transfer instrument of the user in their stead. First, the present invention generates an NFT for the resource transfer instrument the user wishes to use. Next, to allow a trusted dependent to execute the resource transfer in place of the user, the present invention enables the creation of a virtual token for the NFT. The user may establish limits on the virtual token that restricts the resource transfer based on amount of funds allowed per transfer, number of uses of the virtual token, and/or the like. In addition, the user may require the trusted dependent to verify their identity by presenting identification credentials at the electronic kiosk when executing the resource transfer on their behalf. Accordingly, the present invention allows the user to create an NFT for each identification credential of the trusted dependent and link the NFTs to the NFT of the resource transfer instrument. Next, when the trusted dependent executes the resource transfer with the virtual token, the present invention determines whether the virtual token is linked to the NFT of the resource transfer instrument and if so, requests additional authentication information from the trusted dependent. At this time, the trusted dependent may present the identification credential for authentication. Once the trusted dependent presents the identification credential, the present invention may determine whether there the identification credential matches any of the pre-existing NFTs that are linked to the NFT of the resource transfer instrument. By verifying the virtual token and the identification credential presented by the trusted dependent, the present invention may allow the trusted dependent to execute the resource transfer on behalf of the user.

FIG. 1 presents an exemplary block diagram of the system environment for virtualization of non-fungible tokens 100, in accordance with an embodiment of the invention. FIG. 1 provides a unique system that includes specialized servers and system communicably linked across a distributive network of nodes required to perform the functions of the process flows described herein in accordance with embodiments of the present invention.

As illustrated, the system environment 100 includes a network 110, a system 130, and a user input device 140. In some embodiments, the system 130, and the user input device 140 may be used to implement the processes described herein, in accordance with an embodiment of the present invention. In this regard, the system 130 and/or the user input device 140 may include one or more applications stored thereon that are configured to interact with one another to implement any one or more portions of the various user interfaces and/or process flow described herein.

In accordance with embodiments of the invention, the system 130 is intended to represent various forms of digital computers, such as laptops, desktops, video recorders, audio/video player, radio, workstations, servers, wearable devices, Internet-of-things devices, electronic kiosk devices (e.g., automated teller machine devices), blade servers, mainframes, or any combination of the aforementioned. In accordance with embodiments of the invention, the user input device 140 is intended to represent various forms of mobile devices, such as personal digital assistants, cellular telephones, smartphones, augmented reality (AR) devices, virtual reality (VR) devices, extended reality (XR) devices, and other similar computing devices. The components shown here, their connections and relationships, and their functions, are meant to be exemplary only, and are not meant to limit implementations of the inventions described and/or claimed in this document.

In accordance with some embodiments, the system 130 may include a processor 102, memory 104, a storage device 106, a high-speed interface 108 connecting to memory 104, and a low-speed interface 112 connecting to low speed bus 114 and storage device 106. Each of the components 102, 104, 106, 108, 111, and 112 are interconnected using various buses, and may be mounted on a common motherboard or in other manners as appropriate. The processor 102 can process instructions for execution within the system 130, including instructions stored in the memory 104 or on the storage device 106 to display graphical information for a GUI on an external input/output device, such as display 116 coupled to a high-speed interface 108. In other implementations, multiple processors and/or multiple buses may be used, as appropriate, along with multiple memories and types of memory. Also, multiple systems, same or similar to system 130 may be connected, with each system providing portions of the necessary operations (e.g., as a server bank, a group of blade servers, or a multi-processor system). In some embodiments, the system 130 may be a server managed by the business. The system 130 may be located at the facility associated with the business or remotely from the facility associated with the business.

The memory 104 stores information within the system 130. In one implementation, the memory 104 is a volatile memory unit or units, such as volatile random access memory (RAM) having a cache area for the temporary storage of information. In another implementation, the memory 104 is a non-volatile memory unit or units. The memory 104 may also be another form of computer-readable medium, such as a magnetic or optical disk, which may be embedded and/or may be removable. The non-volatile memory may additionally or alternatively include an EEPROM, flash memory, and/or the like. The memory 104 may store any one or more of pieces of information and data used by the system in which it resides to implement the functions of that system. In this regard, the system may dynamically utilize the volatile memory over the non-volatile memory by storing multiple pieces of information in the volatile memory, thereby reducing the load on the system, and increasing the processing speed.

The storage device 106 is capable of providing mass storage for the system 130. In one aspect, the storage device 106 may be or contain a computer-readable medium, such as a floppy disk device, a hard disk device, an optical disk device, or a tape device, a flash memory or other similar solid state memory device, or an array of devices, including devices in a storage area network or other configurations. A computer program product can be tangibly embodied in an information carrier. The computer program product may also contain instructions that, when executed, perform one or more methods, such as those described above. The information carrier may be a non-transitory computer- or machine-readable storage medium, such as the memory 104, the storage device 104, or memory on processor 102.

In some embodiments, the system 130 may be configured to access, via the network 110, a number of other computing devices (not shown) in addition to the user input device 140. In this regard, the system 130 may be configured to access one or more storage devices and/or one or more memory devices associated with each of the other computing devices. In this way, the system 130 may implement dynamic allocation and de-allocation of local memory resources among multiple computing devices in a parallel or distributed system. Given a group of computing devices and a collection of interconnected local memory devices, the fragmentation of memory resources is rendered irrelevant by configuring the system 130 to dynamically allocate memory based on availability of memory either locally, or in any of the other computing devices accessible via the network. In effect, it appears as though the memory is being allocated from a central pool of memory, even though the space is distributed throughout the system. This method of dynamically allocating memory provides increased flexibility when the data size changes during the lifetime of an application and allows memory reuse for better utilization of the memory resources when the data sizes are large.

The high-speed interface 108 manages bandwidth-intensive operations for the system 130, while the low speed controller 112 manages lower bandwidth-intensive operations. Such allocation of functions is exemplary only. In some embodiments, the high-speed interface 108 is coupled to memory 104, display 116 (e.g., through a graphics processor or accelerator), and to high-speed expansion ports 111, which may accept various expansion cards (not shown). In such an implementation, low-speed controller 112 is coupled to storage device 106 and low-speed expansion port 114. The low-speed expansion port 114, which may include various communication ports (e.g., USB, Bluetooth, Ethernet, wireless Ethernet), may be coupled to one or more input/output devices, such as a keyboard, a pointing device, a scanner, or a networking device such as a switch or router, e.g., through a network adapter.

The system 130 may be implemented in a number of different forms, as shown in FIG. 1 . For example, it may be implemented as a standard server, or multiple times in a group of such servers. Additionally, the system 130 may also be implemented as part of a rack server system or a personal computer such as a laptop computer. Alternatively, components from system 130 may be combined with one or more other same or similar systems and an entire system 130 may be made up of multiple computing devices communicating with each other.

FIG. 1 also illustrates a user input device 140, in accordance with an embodiment of the invention. The user input device 140 includes a processor 152, memory 154, an input/output device such as a display 156, a communication interface 158, and a transceiver 160, among other components. The user input device 140 may also be provided with a storage device, such as a microdrive or other device, to provide additional storage. Each of the components 152, 154, 158, and 160, are interconnected using various buses, and several of the components may be mounted on a common motherboard or in other manners as appropriate.

The processor 152 is configured to execute instructions within the user input device 140, including instructions stored in the memory 154. The processor may be implemented as a chipset of chips that include separate and multiple analog and digital processors. The processor may be configured to provide, for example, for coordination of the other components of the user input device 140, such as control of user interfaces, applications run by user input device 140, and wireless communication by user input device 140.

The processor 152 may be configured to communicate with the user through control interface 164 and display interface 166 coupled to a display 156. The display 156 may be, for example, a TFT LCD (Thin-Film-Transistor Liquid Crystal Display) or an OLED (Organic Light Emitting Diode) display, or other appropriate display technology. The display interface 156 may comprise appropriate circuitry and configured for driving the display 156 to present graphical and other information to a user. The control interface 164 may receive commands from a user and convert them for submission to the processor 152. In addition, an external interface 168 may be provided in communication with processor 152, so as to enable near area communication of user input device 140 with other devices. External interface 168 may provide, for example, for wired communication in some implementations, or for wireless communication in other implementations, and multiple interfaces may also be used.

The memory 154 stores information within the user input device 140. The memory 154 can be implemented as one or more of a computer-readable medium or media, a volatile memory unit or units, or a non-volatile memory unit or units. Expansion memory may also be provided and connected to user input device 140 through an expansion interface (not shown), which may include, for example, a SIMM (Single In Line Memory Module) card interface. Such expansion memory may provide extra storage space for user input device 140 or may also store applications or other information therein. In some embodiments, expansion memory may include instructions to carry out or supplement the processes described above and may include secure information also. For example, expansion memory may be provided as a security module for user input device 140 and may be programmed with instructions that permit secure use of user input device 140. In addition, secure applications may be provided via the SIMM cards, along with additional information, such as placing identifying information on the SIMM card in a non-hackable manner. In some embodiments, the user may use the applications to execute processes described with respect to the process flows described herein. Specifically, the application executes the process flows described herein.

The memory 154 may include, for example, flash memory and/or NVRAM memory. In one aspect, a computer program product is tangibly embodied in an information carrier. The computer program product contains instructions that, when executed, perform one or more methods, such as those described herein. The information carrier is a computer-or machine-readable medium, such as the memory 154, expansion memory, memory on processor 152, or a propagated signal that may be received, for example, over transceiver 160 or external interface 168.

In some embodiments, the user may use the user input device 140 to transmit and/or receive information or commands to and from the system 130 via the network 110. Any communication between the system 130 and the user input device 140 (or any other computing devices) may be subject to an authentication protocol allowing the system 130 to maintain security by permitting only authenticated users (or processes) to access the protected resources of the system 130, which may include servers, databases, applications, and/or any of the components described herein. To this end, the system 130 may require the user (or process) to provide authentication credentials to determine whether the user (or process) is eligible to access the protected resources. Once the authentication credentials are validated and the user (or process) is authenticated, the system 130 may provide the user (or process) with permissioned access to the protected resources. Similarly, the user input device 140 (or any other computing devices) may provide the system 130 with permissioned to access the protected resources of the user input device 130 (or any other computing devices), which may include a GPS device, an image capturing component (e.g., camera), a microphone, a speaker, and/or any of the components described herein.

The user input device 140 may communicate with the system 130 (and one or more other devices) wirelessly through communication interface 158, which may include digital signal processing circuitry where necessary. Communication interface 158 may provide for communications under various modes or protocols, such as GSM voice calls, SMS, EMS, or MMS messaging, CDMA, TDMA, PDC, WCDMA, CDMA2000, or GPRS, among others. Such communication may occur, for example, through radio-frequency transceiver 160. In addition, short-range communication may occur, such as using a Bluetooth, Wi-Fi, or other such transceiver (not shown). In addition, GPS (Global Positioning System) receiver module 170 may provide additional navigation- and location-related wireless data to user input device 140, which may be used as appropriate by applications running thereon, and in some embodiments, one or more applications operating on the system 130.

The user input device 140 may also communicate audibly using audio codec 162, which may receive spoken information from a user and convert it to usable digital information. Audio codec 162 may likewise generate audible sound for a user, such as through a speaker, e.g., in a handset of user input device 140. Such sound may include sound from voice telephone calls, may include recorded sound (e.g., voice messages, music files, etc.) and may also include sound generated by one or more applications operating on the user input device 140, and in some embodiments, one or more applications operating on the system 130.

Various implementations of the systems and techniques described here can be realized in digital electronic circuitry, integrated circuitry, specially designed ASICs (application specific integrated circuits), computer hardware, firmware, software, and/or combinations thereof. These various implementations can include implementation in one or more computer programs that are executable and/or interpretable on a programmable system including at least one programmable processor, which may be special or general purpose, coupled to receive data and instructions from, and to transmit data and instructions to, a storage system, at least one input device, and at least one output device.

These computer programs (also known as programs, software, software applications or code) include machine instructions for a programmable processor and can be implemented in a high-level procedural and/or object-oriented programming language, and/or in assembly/machine language. As used herein, the terms “machine-readable medium” “computer-readable medium” refers to any computer program product, apparatus and/or device (e.g., magnetic discs, optical disks, memory, Programmable Logic Devices (PLDs)) used to provide machine instructions and/or data to a programmable processor, including a machine-readable medium that receives machine instructions as a machine-readable signal. The term “machine-readable signal” refers to any signal used to provide machine instructions and/or data to a programmable processor.

To provide for interaction with a user, the systems and techniques described here can be implemented on a computer having a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for displaying information to the user and a keyboard and a pointing device (e.g., a mouse or a trackball) by which the user can provide input to the computer. Other kinds of devices can be used to provide for interaction with a user as well; for example, feedback provided to the user can be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback); and input from the user can be received in any form, including acoustic, speech, or tactile input.

The systems and techniques described here can be implemented in a technical environment that includes a back end component (e.g., as a data server), that includes a middleware component (e.g., an application server), that includes a front end component (e.g., a client computer having a graphical user interface or a Web browser through which a user can interact with an implementation of the systems and techniques described here), or any combination of such back end, middleware, or front end components.

As shown in FIG. 1 , the components of the system 130 and the user input device 140 are interconnected using the network 110. The network 110, which may be include one or more separate networks, be a form of digital communication network such as a telecommunication network, a local area network (“LAN”), a wide area network (“WAN”), a global area network (“GAN”), the Internet, or any combination of the foregoing. It will also be understood that the network 110 may be secure and/or unsecure and may also include wireless and/or wired and/or optical interconnection technology.

In accordance with an embodiments of the invention, the components of the system environment 100, such as the system 130 and the user input device 140 may have a client-server relationship, where the user input device 130 makes a service request to the system 130, the system 130 accepts the service request, processes the service request, and returns the requested information to the user input device 140, and vice versa. This relationship of client and server typically arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other.

It will be understood that the embodiment of the system environment 100 illustrated in FIG. 1 is exemplary and that other embodiments may vary. As another example, in some embodiments, the system environment may include more, fewer, or different components. As another example, in some embodiments, some or all of the portions of the system environment 100 may be combined into a single portion. Likewise, in some embodiments, some, or all of the portions of the system 130 may be separated into two or more distinct portions.

FIG. 2 illustrates a process flow for virtualization of non-fungible tokens 200, in accordance with an embodiment of the invention. As shown in block 202, the process flow includes receiving, via a first user input device, a resource transfer request using a virtual token from a first user. As described herein, the first user may be the trusted dependent who is authorized to execute a resource transfer on behalf of the second user using a virtual token. A virtual token may be a digital representation of a value or utility that may be issued by the second user to the first user to represent a payment instrument associated with the second user. The first user may thus initiate resource transfer requests on behalf of the second user using the virtual token.

The virtual token and the resource transfer instrument are linked using NFT technology. To establish such a link, the system may be configured to first generate an NFT for the resource transfer instrument. Once the NFT is generated, the system may then be configured to electronically link the virtual token to the NFT. To generate the NFT for the resource transfer instrument, the system may be configured to receive, from a second user input device, a first request to generate an NFT a specific resource transfer instrument. In some embodiments, the second user may identify specific resource transfer instruments for which they would like to have an NFT generated. In response, the system may be configured to initiate an NFT generator on the identified resource transfer instrument to generate the NFT. Once the NFT is generated, the system may be configured to record the NFT associated with the resource transfer instrument in a distributed ledger. In this regard, the system may be configured to generate a new transaction object (e.g., block) for the NFT. Each transaction object may include the NFT (e.g., NFT for the resource transfer instrument), a nonce—a randomly generated 32-bit whole number when the transaction object is created, and a hash value wedded to that nonce. Once generated, the NFT is considered signed and forever tied to its nonce and hash. Then, the system may be configured to deploy the new transaction object for the NFT on the distributed ledger. In some embodiments, when new transaction object is deployed on the distributed ledger, a distributed ledger address is generated for that new transaction object, i.e., an indication of where it is located on the distributed ledger. This distributed ledger address is captured for recording purposes. In response, the system may be configured to generate a notification for display on the second user input device indicating that the new transaction object has been created for the NFT in the distributed ledger.

As described herein, the second user may generate the virtual token to allow the first user to execute resource transfers on their behalf. Accordingly, the system may be configured to receive, from the second user input device, a second request to generate the virtual token for the NFT associated with the resource transfer instrument. In response, the system may be configured to generate, using a virtual token generator, the virtual token. In some embodiments, the virtual token may be electronically linked to the NFT associated with the resource transfer instrument by storing a virtual token identifier—a unique combination of a sequence of strings, characters, and numerals that may be used to identify and/or refer to a virtual token such as hash values, hash codes, digests, and/or the like—in one of many metadata layers of the NFT. As described herein, the metadata layer(s) of the NFT may include information that reflects the essential properties of the resource, including, name, description, value, and/or anything else relate to the resource that the NFT generator deems as important. Accordingly, the system may be configured to generate, using the NFT generator, a second metadata layer for the NFT associated with the resource transfer instrument. In this second metadata layer, the system may be configured to store the virtual token identifier.

In some embodiments, the second user may wish to create virtual tokens for resource transfer instruments that are previously associated with NFTs. These NFTs are already recorded on the distributed ledger and cannot not be modified. Any modification of such NFTs (e.g., addition of a second metadata layer to store the virtual token identifier) will require re-recording the modified NFT in the distributed ledger. However, if the second user wishes to create virtual tokens for resource transfer instruments that do not have existing NFTs, the virtual tokens may be electronically linked by generating the second metadata layer to store the virtual token identifier at the time the NFT for the resource transfer instrument is created.

In some embodiments, the system may be configured to allow the second user to enable a multi-factor authentication protocol to ensure that the individual attempting to execute the resource transfer request is indeed the first user. To this end, the system may be configured to store an NFT credential descriptor associated with the first user in the NFT associated with the resource transfer instrument. The NFT credential descriptor may be a data element that is used to describe and/or identify a pre-authorized authentication credential associated with the first user. For example, if the authentication credential is a driver's license of the first user, the NFT credential descriptor may identify the type of authentication credential, i.e., driver's license and information identifying the first user, i.e., license number, name, address, and/or the like. To this end, the system may be configured to receive, from the second user input device, the NFT credential descriptor for the virtual token. In response to receiving the NFT credential descriptor, the system may be configured to generate, using the NFT generator, the first metadata layer for the NFT associated with the resource transfer request. In response to generating the first metadata layer, the system may be configured to store the NFT credential descriptor for the virtual token in the first metadata layer.

Next, as shown in block 204, the process flow includes retrieving the NFT associated with the resource transfer instrument in response to receiving the resource transfer request. In this regard, the system may be configured to capture the information associated with the virtual token from the resource transfer request. Having captured the information associated with the virtual token, the system may be configured to determine a match between the captured information and a virtual token identifier. As described herein, the virtual token identifier is stored in the metadata layer(s) of the NFT associated with the resource transfer instrument. If the virtual token matches a virtual token identifier, the corresponding NFT is identified and retrieved. On the other hand, if the virtual token does not match a virtual token identifier, the resource transfer request may be denied.

Next, as shown in block 206, the process flow includes retrieving an NFT credential descriptor for the resource transfer request from a first metadata layer of the NFT associated with the resource transfer instrument. As described herein, the NFT credential descriptor describes the type of authentication credential required from the first user for authorization to execute the resource transfer request. In response to retrieving the NFT credential descriptor, the system may be configured to initiate the multi-factor authentication protocol.

Next, as shown in block 208, the process flow includes receiving an authentication credential from the first user. In some embodiments, the system may be configured to receive the authentication credential from the first user in response to the initiation of the multi-factor authentication protocol. In one aspect, the system may be configured to scan the authentication credential. Those skilled in the art will appreciate that various means of presentment and fulfillment of authentication credentials for multi-factor authentication may be implemented and configured as needed without departing from the scope and spirit of the invention.

Next, as shown in block 210, the process flow includes determining whether the authentication credential matches an NFT credential descriptor that is electronically linked to the NFT associated with the resource transfer instrument.

Next, as shown in block 212, the process flow includes authorizing the resource transfer request based on at least determining that the authentication credential matches an NFT credential descriptor that is electronically linked to the NFT associated with the resource transfer instrument. In some embodiments, in addition to determining that the authentication credential matches the NFT credential descriptor, the system may be configured to determine whether the resource transfer request is permissible within predefined parameters associated with the virtual token. Accordingly, the system may be configured to retrieve one or more resource transfer parameters associated with the virtual token. Next, the system may be configured to determine that the resource transfer request meets the one or more resource transfer parameters. In response, the system may be configured to authorize the resource transfer request based on at least determining that the resource transfer request meets the one or more resource transfer parameters.

As will be appreciated by one of ordinary skill in the art in view of this disclosure, the present invention may include and/or be embodied as an apparatus (including, for example, a system, machine, device, computer program product, and/or the like), as a method (including, for example, a business method, computer-implemented process, and/or the like), or as any combination of the foregoing.
